Ohaus - 30390261 - ASTM Individual Reference Calibration Weight 2P ASTM 1kg UC Accrd TR
Features
ASTM Individual Reference Calibration Weights
Troemner UltraClass offers high accuracy with tight tolerances and uncertainties of less than 1/4 of the tolerance. Weight surfaces meet or exceed ASTM and have a highly polished finish. Available in high grade stainless steels including Troemner Alloy 8 which possesses closely controlled density, extremely low magnetic properties, good stability, and resistance to corrosion. Available with certificate options traceable to NIST, including ISO/IEC 17025 accredited certification or traceable certification to aid in meeting SOP and regulatory requirements.
Applications
Use as a primary reference for calibrating other mass standards and use for traceability between national mass standards and ASTM Class 1 weights and lower. This class is appropriate for calibrating high-precision balances with readability as low as 0.01 mg.
Construction
One-piece
Design Features
Weights 50 kg through 1 g are cylindrical with handling knob. Weights 500 mg and below are flat with one end turned up for easy handling.
